The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.
In 2020, New York City's Mayor’s Office of Resiliency initiated an engagement process, called the Climate Knowledge Exchange, to align research with climate resiliency and adaptation needs. This report is the first in an annual series that will maintain a public agenda for climate research in NYC. The report communicates NYC’s research needs to external partners, including academic scientists, federal researchers, philanthropic foundations, and community organizations. This in turn will catalyze new and creative partnerships to develop credible and actionable research products that address NYC’s most pressing climate challenges. The report includes the engagement methodology and survey text used with various agencies.
To plan for future sea level rise, Miami-Dade County relies on the 2019 Unified Sea Level Rise Projection for Southeast Florida developed by the Southeast Florida Regional Climate Change Compact. These projections are revised every five years to ensure they reflect the best available science. Based on these consensus projections, they expect sea levels to be approximately two feet higher 40 years from 2019 levels and continue rising beyond that.
Hotter weather, stronger typhoons, coral reef death, and physical and mental health risks are among the major challenges detailed in this report on climate change in the Commonwealth of the Northern Mariana Islands (CNMI). Threatened resources include high-value coastal infrastructure and the millions of dollars that ocean ecosystems add to the CNMI economy annually. This report provides guidance for decision makers seeking to better understand the implications of climate variability and change for CNMI and its communities and identifies the additional information and research needed to support responses that enhance resilience and help CNMI to withstand the changes to come.
This report highlights the equity implications of sea level rise in the first nationwide assessment of risk to the country’s affordable housing supply. As climate change causes sea levels to rise, the number of affordable housing units at risk of coastal flooding is projected to more than triple to nearly 25,000 nationwide over the next 30 years.
Climate change is already impacting or is anticipated to impact nearly every facet of the economy, including infrastructure, agriculture, residential and commercial property, human health, and labor productivity. Over time, if significant action is not taken to check rising global average temperatures, climate change impacts could impair the productive capacity of the economy and undermine its ability to generate employment, income, and opportunity. This reality poses complex risks for the U.S. financial system.
The world continues to emit greenhouse gases while the planet's climate is changing faster than ever. This report intends to take up the latest and most essential scientific findings published in an extraordinary year—the climate science year in review.
The Fish and Wildlife Relevancy Roadmap is a practical guide that state and provincial fish and wildlife conservation agencies can use to overcome barriers to broader relevance, public engagement, and support. The roadmap is not prescriptive and provides multiple pathways to respond to the diverse social, economic, demographic, political, and environmental changes that states and provinces face. The Roadmap was developed by a team of over 60 leaders from state, federal, provincial, and private conservation organizations and others with an interest in conservation.
Alaska has recently experienced profound environmental change related to extreme weather events and deviations from the historical climate. Sustained warmth, sea ice loss, coastal flooding, river flooding, and major ecosystem changes have impacted the daily lives of Alaskans around the state. The International Arctic Research Center and the University of Alaska Fairbanks have documented these changes, and are providing individuals, Alaska businesses, communities, government, and others with the resources they need to better assess impacts and develop adaptation strategies.
The Beloved Community is a vision for our future where all people share equally in the wealth and bounty of the earth, where we protect its abundance, diversity, and beauty for future generations. In this vision of liberation, racism, exploitation, and domination are replaced by democracy, cooperation, interdependence, and love. To get there, we pursue transformative, systems-change solutions. What do we mean by this? The root causes of the problems our communities face—like climate change, racism, and economic inequality—are all deeply connected. Since the problems are connected, so are the solutions. The purpose of this toolkit is to put us on the path toward achieving this vision. Through the context of building equity and resilience into climate adaptation planning, we introduce strategies to transform our communities and, by extension, society. Our ultimate goal is to create lasting and systemic change. At the same time, we recognize the urgency of the issues our communities face and the need to take action now. That is why we pursue change at every scale—from policy changes to community-based projects—to institute the transformative change we need to uphold our vision of the beloved community.
The guidance provided by this report is designed to help all communities create disaster debris management plans. It assists communities in planning for natural disaster debris before disasters—such as hurricanes, earthquakes, tornadoes, volcanoes, floods, wildfires, and winter storms—occur by providing useful, relevant information intended to increase community preparedness and resiliency. The report includes recommended components of a debris management plan, suggested management options for various natural disaster debris streams, a collection of case studies that highlights how several communities prepared for and managed debris generated by recent natural disasters, resources to consult in planning for natural disasters, and the EPA’s recommended pre-incident planning process to help prepare communities for effective disaster debris management.
This plan represents the efforts of the State of Minnesota in fulfilling the responsibility for hazard mitigation planning. The purpose of this plan is to identify the state’s major hazards, assess the vulnerability to those hazards, and take steps to reduce vulnerability using the technical and program resources of Minnesota agencies. The process has included consideration of current and expected future impacts from Minnesota’s already changing climate, as relevant to hazard mitigation planning. The plan identifies goals and recommends actions and initiatives for the state government to adapt to, reduce, and/or prevent injury and damage from hazardous events.
This report offers the first national assessment of the scope and consequences of urban flooding in the United States. Researchers analyzed available data concerning urban flooding, surveyed municipal flood and stormwater managers, and met with professionals whose disciplines intersect with urban flooding at the local, state, and national level. The research team's findings affirm that urban flooding is a national and significant source of economic loss, social disruption, and housing inequality. This report presents the full results of the study, addresses governance issues that affect urban flood risk reduction, examines critical challenges, and offers recommendations for actions.
The Global Change Research Act of 1990 mandates that the U.S. Global Change Research Program deliver a report to Congress and the President no less than every four years that “1) integrates, evaluates, and interprets the findings of the Program…; 2) analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and 3) analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years.” The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report. Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods. This assessment was written to help inform decision makers, utility and natural resource managers, public health officials, emergency planners, and other stakeholders by providing a thorough examination of the effects of climate change on the United States.
Shorelines with high boat wake and wave energy face especially rapid erosion and habitat loss. A new living shoreline design from researchers at the University of Florida and the Guana Tolomato Matanzas Reserve that uses gabion-breaks has proven successful in high-energy environments. The gabion-break design uses two lines of defense to reduce erosion along the marsh edge—porous wooden breakwalls placed in front of structures that will foster oyster growth. This manual for restoration practitioners describes a collaborative research project that tested gabion-breaks along the Atlantic Intracoastal Waterway in northeast Florida. It discusses the project’s results and details the steps to use gabion-breaks, including planning, design, maintenance, monitoring, and costs.
This special report from the Intergovernmental Panel on Climate change describes the impacts of global warming of 1.5 °C above pre-industrial levels. The report also describes potential global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
This report focuses on identifying, developing, and implementing strategies to increase the power system’s resilience in the face of events that can cause large-area, long-duration outages: blackouts that extend over multiple service areas and last several days or longer. Resilience is not just about lessening the likelihood that these outages will occur; it is also about limiting the scope and impact of outages when they do occur, restoring power rapidly afterwards, and learning from these experiences to better deal with events in the future.
This guidebook results from the culmination of a year of dialogue among diverse stakeholders in southeastern Connecticut who defined challenges and solutions from extreme weather, climate change, and shifting social and economic conditions. Participants included representatives from nine municipalities, public and private utilities, public health departments, chambers of commerce, major employers, conservation organizations, academic institutions, community non-profits, and state agencies, among others. The dialogue captured six themed planning sectors (water, food, ecosystem services, transportation, energy, and regional economy) in a process that used surface and integrated solutions to address singular and multiple challenges across planning sectors. The guidebook provides a quick reference resource to help shape and inform actions that will advance a regional resilience framework for southeastern Connecticut; an accompanying Summary of Findings captures the project's final outcomes and conclusions, as well as providing a comprehensive account of the objectives, process, and details.
This report summarizes findings from a workshop held in El Paso, Texas, on July 13, 2016. The El Paso-Juárez-Las Cruces region is home to approximately 2.4 million people, most of whom are living in or near the urban centers of Ciudad Juárez (Chihuahua), El Paso, and Las Cruces (New Mexico). These cities share characteristics, such as a high proportion of residents of Hispanic origin, median income below the U.S. national average, and a range of climate-related environmental issues that include drought, flooding, air pollution, dust storms, and frequent occurrences of extremely high temperatures during the late spring and early summer. With hotter temperatures and more frequent and persistent heat waves projected for the El Paso-Juárez-Las Cruces region, it is critical to develop more robust systems of institutions, social learning, and partnerships to understand risks and strengthen public health resilience.
This guide describes how Climate Central's Surging Seas web tool can be used to support activities that receive points within the Federal Emergency Management Agency's (FEMA) Community Rating System (CRS) program. It is informed by conversations with local CRS coordinators and implementers, and with FEMA CRS representatives. The guide provides step-by-step instructions on how to access and obtain information and downloads from the Surging Seas tool that could be utilized within specific CRS activities in FEMA’s Coordinator’s Manual (FIA-15/2013).
The Office of Management and Budget (OMB), in collaboration with the Council of Economic Advisers (CEA), has attempted to quantify the fiscal risks posed by climate change for the Federal Government. To date, this effort has yielded two primary conclusions: first, that our current understanding of the fiscal risks of climate change is nascent, limited in scope, and subject to significant uncertainty; and second, that the evidence available thus far indicates the fiscal risks to the Federal Government could be very significant over the course of this century without ambitious action to reduce greenhouse gas emissions (GHGs) and adapt our communities to a changing climate.
This report outlines the contours of fiscal risk through five program-specific assessments: crop insurance, health care, wildfire suppression, hurricane-related disaster relief, and Federal facility flood risk. These programs were assessed because they are directly influenced by climate change, they have strong links to the Federal Budget, and quantitative scientific and economic models regarding the likely magnitude of impacts were available. This report also considers potential impacts to Federal revenues.
This Web toolkit raises airport operator awareness about vulnerabilities caused by significant weather events. The toolkit helps airports develop more robust contingency and recovery plans, in addition to their airport emergency plans. The toolkit focuses on events that are “rare but plausible”; that is, events that may have happened in the distant past, or in adjacent geographic areas, but are not common event types at the airport itself, and therefore may not be in the forefront of the airport managers’ minds.
This document provides final guidance for federal agencies on how to consider the impacts of their actions on global climate change in their National Environmental Policy Act (NEPA) reviews, providing a framework for agencies to consider both the effects of a proposed action on climate change, as indicated by its estimated greenhouse gas emissions, and the effects of climate change on a proposed action. The memorandum applies to all types of proposed federal agency actions that are subject to NEPA analysis and guides agencies on how to address the greenhouse gas emissions from federal actions and the effects of climate change on their proposed actions within the existing NEPA regulatory framework.
The State of Maine is experiencing shifts in atmospheric and oceanographic conditions that put it at the precipice of abrupt climate change. This report—part of the Department of Homeland Security's Regional Resiliency Assessment Program (RRAP)—focuses on the local and regional consequences of climate disruptions and their impacts on critical infrastructure in the Casco Bay region, the most developed and populous region in Maine. The report identifies vulnerabilities that may potentially affect the region’s ability to maintain its critical infrastructure systems and recover from the impacts of climate change.
The SECURE Water Report identifies climate change as a growing risk to Western water management and cites warmer temperatures, changes to precipitation, snowpack and the timing and quality of streamflow runoff across major river basins as threats to water sustainability. Water supply, quality and operations; hydropower; groundwater resources; flood control; recreation; and fish, wildlife and other ecological resources in the Western states remain at risk.
This handbook (USGS Professional Paper 1815) was designed as a guide to the science and simulation models for understanding the dynamics and impacts of sea level rise on coastal ecosystems. Coastal land managers, engineers, and scientists can benefit from this synthesis of tools and models that have been developed for projecting causes and consequences of sea level change on the landscape and seascape.
This report—the first phase of the Department of the Interior (DOI) assessment effort for Hurricane Sandy projects—was developed for DOI by a metrics expert group of physical and ecological scientists and socioeconomic experts who recommended performance metrics for measuring changes in resilience resulting from the DOI-sponsored projects. It identifies natural and artificial coastal features most affected by Hurricane Sandy along the Northeast coast—such as marshes, beaches, and estuaries—and recommended metrics that would indicate resilience change in those features.
In 1993, Portland was the first U.S. city to create a local action plan for cutting carbon. Portland’s Climate Action Plan is a strategy to put Portland and Multnomah County on a path to achieve a 40 percent reduction in carbon emissions by 2030 and an 80 percent reduction by 2050 (compared to 1990 levels). The 2015 Climate Action Plan builds on the accomplishments to date with ambitious new policies, fresh research on consumption choices, and engagement with community leaders serving low-income households and communities of color to advance equity through the City and County’s climate action efforts.
This report builds on Maine’s earlier report from 2009—it is not intended as a comprehensive revision of all aspects of the original report. This update focuses on highlights of the understanding in 2015 of past, present, and future trends in key indicators of a changing climate specific to Maine, and recent examples of how Maine people are experiencing these changes.
Find out how hometowns across the United States are building their resilience to climate change. Two women who studied climate change science and policy in graduate school took a three-month road trip to find out what climate change adaptation looks like in the United States. They visited more than 30 communities preparing for climate change and documented what they learned in blogs and through media reports. This report describes six big lessons from the ongoing adaptation work they saw across the country.
This Synthesis Report summarizes the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). This report distills, synthesizes, and integrates the key findings of the three IPCC Working Group contributions—The Physical Science Basis; Impacts, Adaptation, and Vulnerability; and Mitigation of Climate Change—to the AR5 for the benefit of decision makers in government, the private sector, and the general public. The report also includes findings from two Special Reports released in 2011: Renewable Energy Sources and Climate Change Mitigation and Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation. The Synthesis Report confirms that climate change caused by human activities is having impacts on ecosystems and human well-being across the U.S. and around the world.
This study investigates how climate change will impact the telecommunications and data center services sector. The report looks not only at the headline-grabbing impacts of extreme weather events, such as those incurred by Hurricane Sandy, but also the risks brought on by slow-onset, gradual changes to the base climate.
This report outlines 100 recommendations to help improve federal programs and their ability to prepare for climate change, drawing from a series of workshops with leading federal, state, and local officials and building upon lessons learned post-disaster in New Orleans (following Hurricane Katrina), New York (following Hurricane Sandy), and Vermont (after Hurricane Irene). The report identifies more than 30 federal programs, initiatives, and laws that can be used to prepare for extreme events such as storms, floods, and heat waves as well as rising seas. This report informed the White House's State, Local, and Tribal Leaders Task Force on Climate Preparedness and Resilience.
This plan—an update to the 2009 California Climate Adaptation Strategy—augments previously identified strategies in light of advances in climate science and risk management options.
The National Climate Assessment assesses the science of climate change and its impacts across the United States, now and throughout this century. It documents climate change-related impacts and responses for various sectors and regions, with the goal of better informing public and private decision making at all levels.
The assessment draws from a large body of scientific peer-reviewed research, technical input reports, and other publicly available sources; all sources meet the standards of the Information Quality Act. The report was extensively reviewed by the public and experts, including a panel of the National Academy of Sciences, the 13 federal agencies of the U.S. Global Change Research Program, and the Federal Committee on Environment, Natural Resources, and Sustainability.
